Hazards and Protection.
Storage
Keep tightly closed. Keep away from heat and open flame. Store in a cool dry place.
Protection
Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.
Incompatibilities
Acids, Acid chlorides, Acid anhydrides, Strong oxidizing agents Carbon dioxide.
Decomposition
Thermal decomposition may produce carbon monoxide, carbon dioxide, and nitrogen oxides.

Fire.
Flash Point,°C
59.5
Fire fighting
Small Fires: Dry chemical, CO2, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam.
Fire potential
Flammable/combustible material. May be ignited by heat, sparks or flames.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin Inhalation may result in spasm, inflammation and edema of the larynxand bronchi, chemical pneumonitis, and pulmonary edema Symptoms of exposure may include burning sensation, coughing wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. To the best of our knowledge, the chemical, physical and toxicological properties have not been thoroughly investigated.
   Ingestion
May cause toxic effects.
   Inhalation
Vapors may cause dizziness or suffocation. May cause toxic effects.
   Skin
Contact with substance may cause severe burns.
   Eyes
See Skin.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
   Eyes
In case of contact with substance, immediately flush with running water for at least 20 minutes.
